Acne in adult women is often hard to treat. One study showed that 80 percent of women prescribed antibiotics for acne receive no benefits from the drugs, Shinkai said. In these cases, the acne may stem from normal hormonal changes, such as those that occur around the menstrual cycle, or from a true hormonal disorder. For many of these women, medications that target hormones, rather than skin bacteria, would provide the most help, Shinkai said.
Most people who get acne start having it in their early teens. This is when the oil glands in the body start making more sebum (oil). Some people also have too many sticky skin cells. In people with acne, these cells mix with the oil and plug up the hair follicles in the skin. These plugs trap bacteria (germs) in the follicles, which can cause the follicles to swell. Tender red bumps are the result. In acne, what start as small red bumps can turn into pimples and even cysts.
